"AA mode possible with manual lenses?"


US
          

I'm thinking about getting an AA-mode capable speedlight for use with my D1h due to the extended aperture range available over my SB-25's regular A mode and the exposure compensation option. It is my understanding that AA mode will work with any aperture setting and either manual or aperture priority modes. But will AA mode work with manual focus AI and AIS lenses? If not, this will be a deal-breaker. I want to use it with a manual telephoto zoom at f/2.8 and f/4.

An undeniable paradox: To think that there is any such thing as an absolute rule is at worst naïve, and at best, shortsighted. There is no such thing as an always-true, all context- or situation-salient, absolute rule that always holds true…including this one!

Well, I just found out that AA mode is not available with the SB-28DX when using manual lenses. Can anyone with the SB-800 confirm that the same is or is not true for the SB-800?

I don't have a MF lens with me, but I'd be surprised if AA could work, because AA mode depends on have aperture info sent to the flash. Without a cpu, I don't think that's feasible...

I don't know about other flashes, but on my SB-800 I can manually set the aperture on the flash when I am using an MF lens.

AA mode requires the Distance information only a D, G, Dx lens can provide see page 38 of SB 800 manual. (that is if you understand Greek or geek talk)

I see - I was thinking of A (Non-TTL Auto mode). Given the camera requirements for AA mode, it looks like any camera capable of AA mode is also capable of TTL mode. Why would you want to use AA mode instead of TTL mode?

I believe AA mode does not do a preflash and therefore may reduce people with closed eyes. Nor will it trigger SU-4 slave type units with the pre-flash.

It does pre-flash in AA mode, although the delay between pre-flash and main flash is somewhat shorter (the A mode does not). You can see the double lighting bolt icon on the flash that indicates pre-flash, and it's also somewhere in the manual.

The way I read page 38, you only need a CPU lens, which still excludes most MF lenses, but it's not limited to D/G lenses, I don't see anything about required distance information (it may use it if available, just like TTL mode).

The main advantage of A/AA mode versus TTL I see is with off-camera flash, since the flash won't see the same as the lens. The obvious example is lighting a background with a wireless slave. Since you just want the background correctly exposed, AA mode can work better in this case.
